Bahtinov Focus Masks...  &#149; In 2008 an amateur telescope maker and astronomer ppublished an ingenious new way to easily focus your DSLR, webcam or CCD camera for taking astrophotos. The method is simple, very intuitive and the device has universally been named after the inventor. The Bahtinov Mask.  &#149; Farpoint manufactures this *LIFESAVING* astrophotography tool out of virtually indestructable ABS plastic and comes in two major types and in a range of sizes.  &#149; One mask is a general purpose mask designed to fit refractors and newtonian telescope. The other mask is designed to fit Schmidt Cassegrain telescopes. Both types of mask are available in a range of sizes to cover your needs.

Farpoint FP401 Bahtinov mask

I remember one night I spent four hours trying to get a great photo of a nebula. Through the camera viewfinder it looked like everything was in sharp focus. After coming back inside it turns out that the camera slid slightly in the focuser. It slid just enough to render about 3 hours of time totally wasted! The Farpoint Bahtinov mask is a great way to check your focus and check to make sure your camera did not slip. The time you save will make it well worth the cost. HIGHLY recommended!

Essential! It will pay for itself fast!

There's no reason to spend more as this mask is well made and durable.

Bahtinov Focus Mask for Telescopes

I use this on an astro-tech 6" Ritchey-Chretien and an astro tech 6" imaging newtonian. This makes it easy (and the cheapest of all the possible ways) to achieve tack-sharp focus.
